Wow! If this is a speedpaint, I think you may be overworking your images a little. Some of them feel noisy to me, or at least lacking in contrast. Here I can more clearly see what you want me to focus on, and it still looks fairly well-detailed.
This is fantastic! I really felt my eyes widen as this wonder appeared on my screen. You've done a lovely job in any way possible! The colours are intense but still fits the theme. The pose is alive and natural. Same goes with the light and shadow, and those details! They're sharp just where we ant to look!
Very imaginative, almost psychodelic picture. Very pleasing to look at - and amazing that you produced this in only 2 1/2h! Please refrain from sleeping until you have produced another fascinating image like this!
