Truth is
It will be pretty hard to trace this on corel draw, considering the resolution of the attachment you added..
I propose to trace all in photoshop and then do the designing in Corel draw.
It just be beautiful designed in corel draw.
Its easier to say... Yes I will do them in corel draw, so as to gain your approval..
It is possible, but to get the best result, photoshop shop will be fine for the tracing. Then I will design with COREL DRAW.
Hope I'm still your guy for this?
