Space Gypsy Sketches

I noticed it had been a while since I made any Space Gypsy related art. I had been meaning to make a comic strip adaptation of the opening of 'The Daytrip To Tower City' but until recently university commitments had kept it on the shelf. But this is what I draw the characters like, just now

I like the way I draw Gemma, Damien and Rekki, but I am not so sure about Leah and Duke. Any tips Space Gypsy fans?

These characters belong to T.J. Askew.
