Hi! my name is Vivek Mudgal. I am from India. I am a self trained artist. I found this site to be very encouraging. I hope that all the creative people on this site will help me point my drawbacks and give there valuable suggestions. Please do visit my site WWW.EXTREMEILLUSTRATIONS.COM for my complete works, and please please give your valuable comments.
As Steel pointed out already, anatomy studies would be great. I do love the dynamics of some of your drawings though. Portraits are a good start, try to push the tones further in those portraits though i think it would give them some great depth. Keep up the good work!
