I learned this and now I will pass this on to you. The important thing to remember is NOT to LET GO of the mouse when you are filling the rose and the background. Enjoy!
First, you need to make an outline for your rose.
In the guide, make a pentagon shape.
TOOL: STRAIT LINE
(You can adapt this to make different flowers by making the sides different lengths, and using other shapes like a square or hexigon.(Example: A daisy has 4 petals and a pitcher plant has one long petal)
Next, make a bunch of smaller pentagons inside each other turning them as you go.
(You don't really want to make a spiral, just make the corners perpendicular to the edges.)
Next, we have to draw the petals.
Using the guide, make each petal individually along the lines of the guide.
Make a small space in between each petal so the lower one can come out between them.
This gives the illusion that they're overlapping.
Make this smaller as you go deeper into the center.
As you start to reach the center, let go of the guide and just start making a spiral.
Try to keep the petal shape though.
Once you've reached the middle, make a small 9 to imply a newly emerging petal. Fix any small annoying mistakes.
In the space between the spiral, draw lines to complete the petals in the same spiral pattern.
Make it so that one petal overlaps one another.
Now for the color.
Choose a base color. This can really be any color you want, but I choose classic red.
Put Alpha (opacity) on 50
With the fill tool, start in the middle and pull it out to the edge.
Draw along the outline all the way around covering the petals on the edge to the best of your ability.
It is very important that you do not let go of the mouse during this part. You could end up with annoying dark lines that you do not need (or want).
Bring it all the way around, Use the eye dropper to get the color of your fill. NOT the actual base color.
With the control specs from the previous step, Fill in those annoying whit spots by going over them a couple times.
Once your done, Use the eye dropper to d=get the color of your outline.
This should be a shade of the color you used as the base. NOT black.
When you got that, set:
Then go over the lines you erase in the previous step.
Next, we are going to shade the petals.
TOOL: AIR BRUSH
SIZE: 10-16 (depends on size of rose)
Start with a color slightly darker then your base. (As shown in step 10)
Save this color.
Shade the area that would be an over lap of the petal. shade a little further out in the middle to show depth.
As you move down the layers, Make the Size slightly smaller, the Color slightly darker, and the Alpha slightly higher.
When you get to the spiraling petals, pay extra attention to where they overlap.
Continue this until you get to an almost black near the center.
When that happens, color in the 9 you made earlier with a Size 6 Airbrush.
Now your done with the rose but now we need to make it pop!
I like to add a nice background to it. This is a good one I like.
COLOR: This should be the first color you saved as your first highlight
Start by making 3 circles in random places not on the rose. go over it a 3 or 4 times to make it deep.
Lower the Size a little bit and make 3 more.
Continue this process until you have 3 size 1 circles. (you may have to go over the small ones more times to make them appear.)
Set a very light color other then the one you used for your rose. I chose blue.
ALPHA: 15(make sure to keep this low)
Go over all the white space with it. Don't be afraid to touch the rose to get all of it filled.
Again, it's very important that you don't let go of the mouse until your all done.
Once you are done, shade over the corners with the same tool for a shadow border.
Shade over the corners a bit more to make the deeper parts darker.
Set the Airbrush at:
Make more small random circles everywhere. Try not to get them on the rose, it looks bad.
Then add your signature!
And, there you have it.
