Interesting characters everyone. I'm sure I wont have any problems drawing them into the backgrounds. They will fit perfectly within the next chapter of U-Speed (part 6). Currently its in the first pages of part 3, but at the rate of page uploads, part 6 will be up around August. I will bump this thread by the time I get the first cameos (first for Tapastic users) to show in the comic so you can play "where's my character" in the pages. XD
Again, thanks everyone. This will be a big help.
