I've already started submitting adult pieces to the art portal, but they'll stay on my profile until someone scouts the work and approves it for the portal. At the moment, I'm keeping it slow, updating about once a day.
Just out of curiosity, how many adults on Newgrounds are in LA? I've been over to Valley Flash, but don't know that many people in LA that work with the program. I'm planning a trip to Digital LA the next time they have an event on Monday (currently I'm working week nights on the side).
The flash work is continuing, very slowly but surely. I'm starting by importing some drawings from the past, and re-creating them in Flash.
Meanwhile, on the drawing table, I have a style sheet of a character I'll use for animation. The beauty of flash and style sheets, is I can create a character, and simply re-use the pieces for future animations.
As for the bike, that's just for fun. It's an idea I had for a chopper with an old Ducati engine. It was a lot of work, and a lot of fun to create.
