This is my first retopology, as I am a newbie. I was wondering about this specific piece on my model. Is this too sloppy? and what do I need to do to make the qads more uniform on the left of the picture?
That’s quite a complex form to start on, I think you may end up keeping adding complexity if you push on how you have started.
Try and break it into separate manageable chunks and just put in edge loops to define them then fill in the gaps after. Also it looks like some of those parts are separate panles so you can do them separately to make life essier.
Id really recomend getting a subscription to blender cookie and following some of those courses first like this one http://cgcookie.com/blender/cgc-courses/hard-surface-weapon-retopology-in-blender/ that’s where I learnt it’s not much to subscribe and you can always unsubscribe.
