Thanks all
Wow I am surprised this generated as much interest as it did!
As for the time I have invested in it.
Its so hard to say. I worked on it over the course of 2 days on and off.
I could do it in an evening if i sat still

I would say 3-4 hours total in painting and finishing maybe less. A lot of that is drying time.
Thats probably more then Many take on a fish like that.
But I am a bit of a slow poke I listen to music sit at my desk and zone out and relax as a paint.
I do a lot of back and forth between reference and always have many projects going at the same time.
