Hello, Ideaz -
Really like these latest entries, particularly #19 and #20. I believe #19 would be easiest to work with, due to its overall rectangular shape.
One modification: I believe the "rocket blast" should go from red/orange to yellow, rather than yellow to red/orange, as it currently is. The current shape is correct, but the gradient should be reversed.
I would also like to see a version of #19 with the exhaust behind the lettering, please.
Thanks!
