Lot of ambition going on here. Not afraid to try the big stuff. Don't ever be afraid to keep pushing like this. In general, everything went by a bit too fast. Hard to take everything in even with a few plays. You certainly are improving, and it shows. Practice is paying off.
I'm sure you can see there are some anatomy issue, drawing in general, etc. Just a matter of more study. Keep pushing along at a steady pace, and you'll be one of the greats.
