The first sketch I did a while ago, and is a basic sketch of a Tavor TAR-21.
Next an M14 EBR (Enhanced Battle Rifle). I started this a while ago and finished today. This is the highest detail sketch that I've done as of yet.
Last is of a TDI Vector, or "Kriss" submachine gun. This one is not a trace, but a physical drawing - done first with pencil, then done over with pen. I then scanned it and added shading. I started the sketch two days ago, touched it up and penned it in yesterday, and then scanned & shaded it today. This is the first pen-job I've done, and you can see the original pen-work from what is completely black.
Thanks for viewing! Please leave feedback if you have something to say :)
