hi, i will show you some tecniques to create sprites.
first search for some 2D models from 64x64 to 256x256
then you need to cut and remove all the grey area of the desired item and make it 64x64 or 128x128 just "cutting it" with the paint cut square tool!
finally when you got the desired item in 64x64 or 128x128 then you will use the resizer to make it 32x32.
and now you got the sprites in 32x32, now go to any image editor like, photoshop, corel, etc.
and do some touches like bright, shadows, contrast.
now you got 32x32 sprites base models.
