no, you will not add blurr to the arms.

Stop blurring, stop sharpening, stop all that. Leave the filters panel alone too, it's not helping.

You also seem to be using the one brush for everything, if you are, stop that.

Your images seem to have a low dpi for your images, and your paintings are incredibly small.

The tones don't make much sense at all, the lighting and shading is negating itself and the overal style and design of everything seems like random objects flung together, with not much thought about adjascent and perpendicular angles or topographical flow.

All in all it's improvement, but you haven't really prgressed to me, you've really just got better at the same thing you allways have been doing.
