For my best day I went with a bit of a double approach, I decided to show "myself" imagining an awesome and ridiculous scenario, like riding a T-rex that shoots rainbows (or lasers) out of his eyes, these are to be added later. On the one hand the T-rex scenario would be the best day ever (I dare you to argue that) and on the other hand listening to music and letting my imagination fly is already a pretty great day.
This is the preliminary sketch but I dont think the finished piece is gonna differ too much from it, probably gonna add a reflection to the glass window and fix that right arm that looks a bit odd. Ill also tighten the lines of course, particularly on the dinosaur.
Any critiques and comments are more than welcome.
