I'm taking a jump into some digital painting and struggling with getting more defined lines to look right. I'm basing it entirely on this Flower from Unsplash.com and have been using the 3 Basic Brushes from CtrlPaint.
Here's my work in progress with and without the veins showing:
To do the veins I've been using the angled brush from the brush pack set down to about 2 or 3 pixels. Shape, Transfer, Smoothing and Build Up are all turned on with my Tablet.
The two dark petals I've done I'm okay with, the one could use that one dark line on at the apex adjusted but overall those two are getting close. The three lighter petals I've done so far however are way off.
Any suggestions on either a technique or brush to help improve the veins?
