I used to draw and paint just as a hobby, then i never increased my habilities. I used to visit deviantart sometimes, but when i saw Benes' work, i thought: "Wow! I found my idol!". And i finally created my account. ^^
No more blah blah blah. Here's my colored version for this amazing Benes' Storm: [link]
Thank you so much, my friend! Well, i must say i'm not an expert, but i've learned a lot since my very start in couloring. I was not good with shadows and lights at all, before i start colouring with a computer. I mean, digital painting allows you to do infinite experimentations without ruinning the whole piece. That been said, don't be afraid to try! Play around with layers opacity, filters, effects, everything that is available. You'll be surprised with the results you can get! And, if you still need some help, just tell me and i'll be glad to give you a hand! Cheers!
