Sbm Progress: SD ZakuII Sniper

To test a new online drawing app, I used an old concept I put aside for a long time.

Honestly, this is an original concept to have a sniper version for ZakuII... more or less inspired by GM Sniper after MS-08 Team

The original one was an incompleted formal scale. To fit into the limited drawing space, I had to use the SD form.
After exporting it, I used Sketchbook to do follow up. That's my latest progress so far.
