Good luck! This ship looks very pretty, and the details are very nice. The larger picture on the right looks a little asymetrical, though; is it meant to be that way? It's only a small nitpick, though; besides that, brilliant.
I know this is an old topic, but just to make sure: Zbrush uses an orthogonal view by default. You can change it to perspective by pressing 'p'. That's probably the weird perspective issue you had there.
thanks sir. well i'm always trying to make it look right. even if its not necessary. especially with concept art... it doesnt always have to look perfect since you only want to present an idea to go on/ahead from.
