A sci-fi rifle. Original base concept was from another artist.
needs more detail, way more detail, well in my opinion thou, because I tend to look forward to a more hard sci-fi aproach of weaponry and design, i always try to make it look as every component of a model has real use.
for instance in your design I would add for instance structure for attachments a sight, althou I love the line flow in it, feels too minimalistic.
