this was a fun project i can tell.....and yes, your lens is nice and sharp.....i especially like the swirl that the straws make.....

i do have some suggestions......

about the overexposed straws on top....since this is a staged shot and easily recreated, look for more sources of light and play with different configuratuions...well distributed light will enable you to have better color saturation throughout your image...also, check out your background just before you press the shutter.....with something as "abstract" as this image, you might want to consider a totally empty background in a color of your choosing....you could used anything from an old bedspread to construction paper....toy with your perspective too as you can see the rubberband holding the end of the straws together....and lastly, the framing is tight...step back a little so that all the ends of the straws are within the frame.....

thanks for sharing and have fun
