reaaaally like the top left one and the one on the right a lot! The one in the bottom left one is cool too just a bit cartoony in my opinion!

That's why I made three different versions ;)

Well done Toraneko. I really like your concept art for Flash.
I think the streamlined dingo in the top left makes an excellent corporate logo and would work well in formal scenarios like letterhead or board member lapel pins; while the cartoon version of Flash in the bottom left would work well in irreverent situations, like the annual con advice comic or a website 404 message.

Quite a handsome logo. :3

Bottom left is cute :>
