My first attemp of drawing weapons, I put a lot of effot especially the dagger :D
I'm a little bit scared if people don't like it.
I suck at drawing

Not bad, not bad..... Though I would add a little more gradients on the blades. So it has more detail

Work on the actual concept and design of the weapons.
The colors can be improved. That's just simple weapons by a beginner.
Nothing much to say.

^ I pretty much would say that.

Also, the scythe's blade is a bit off. It wouldn't be so tall and short like you made it. For an example, look at my RHG's scythe's blade on my signature down here.
