The models look great! A few points to watch out for. 1) Its May 4th today so if you intend on selling these for 'seasonal' events I suggest you upload them atleast 2 months before the date to give people time to set them up for their marketing campaign, otherwise you will probably wait until next year now. 2) The stormtrooper is modelled in T-Pose, however looking at the topology there is no way to skin/rig these in a clean manner. You need to provide these as quad subdivisions with enough flexibility around the elbow/shoulder/knee/hip joints etc. 3) These should definately not be 'Royalty Free' license to avoid getting these taken down with a DMCA request.
