Yo - I love the loose colour work - the only thing I would say is that the first one looks a bit odd because of the size of the dragon. If you look at the body it's almost as if he's riding something with the girth of a dog?
The other thing that's weird about that picture is that he's sat behind the wings instead of say over the shoulders or on the neck - I get that you wanted to show the wings but perhaps there's a slightly different way to approach it?
Otherwise the colour work is really nice well done! And frankly most people probably wouldn't even spot that issue...
Oh and if you want to watch me paint live I recently got introduced to this thing called picarto TV... It's nice to do art and share it - if you have any questions it's great to talk too! I'm painting pretty much 12 hours a day so you'll most likely find me - unless I'm eating
wow, man you're the man haha i'm really impressed by your work, it's really good. Wish i could draw and paint color as well as you do, still have a long trip to achieve this type of illustrations. Keepu up the good work
