My best picture so far

Why in b&w?

I think it's OOF, especially the hand. Also, I don't like the head being cut off.

Not to be all negative, but you might reconsider calling this your best picture.

This is a great picture. The bubble is sharp and that is really what matters in this picture. The motion blur of ther arm, is bringing movement into the picture so that is no problem. I also doesn't need more of the girl to get the context. This cropping works for me. Black and white could be the best version of this picture, if the colours behind the bubble is distracting... it is the shape of the bubble that makes the picture, and that is being brought up in a good way by using b&w. But it would be nice to see the colured version of it.

Well thank you both. i know opinios are like colors, there are lots of them, but i thank you both. I do not have the color one, just by mistake had the camera in BW and also in L mode, so no raw picture.
I agree with you, what i like about it is the motion sensation in it, and that the most important thing in this picture is the bubble.
I also took this one, i hope you also enjoy it
