Is This Ok Or Should I Do Something Different? Thanks.

The main problem I see is the glare on the glass-- it softens it considerably and the reflections of other people are distracting. The white block in the upper left also distracts. That said, it's an interesting photo, I'm just not sure anyone would buy it to hang on their wall because of the technical issues.

I am OK with the glare. Its glass. A small amount of glare is acceptable. The composition could be improved through cropping. I would crop from the top and left until the nose of the seal is about 1/3 of the way into the frame. Be sure to completely crop out the white thing. Having more seal and lees distracting background will help this photo.

You have to move in close to glass to eliminate glare. Also use a circular polarizing filter to reduce glare.

The sea lion - the main subject - isn't the least bit sharp, so if this were my image it would end up in the bin.

Looks better now with the crop. But you can't make a 60 inch print out of this. Not sure how you even got it to exactly 6,000 x 4.000 pixels. Don't enlarge. Don't set any DPI when cropping. And also look at the image a 100% view. This should be offered at post card size and a little larger.

The reflection in the glass would cause me to trash it, if it were mine.

So harsh, I know. I am harsh with myself. I would be cursing that reflection, as I deleted it forever.

I would try to go back and reshoot something like it again, praying that the animal would cooperate a second time.

Of course, that's ME.
