Did I sell the water as a texture? I've studied calm water surfaces and reflections but I've been staring at it for so long I can't tell if it looks right or not.
Yes, definitely, it works the most in the reflection. Less so further out towards the horizon.
Do you feel what I wanted to convey with this? Does the piece appear calm?
I feel calm looking at it.
Did I overdo the looseness thing? I was REALLY boling it down only to the most important details and I am afraid it may not read well.
In my opinion, no. But had you not pointed it out, I would have been content that this was your objective, practice and a study.
Do you notice anything wrong about the lighting? It was quite terryfing to NOT use lines to describe forms.
The answer to this is subjective. Because you've chosen to do it quite stylised, even with a limited palette, I cannot judge on "right" or "wrong" lighting. You could rephrase that to does the form fit the function? Is the lighting appropriate for this scene? And in that, I say yes. But you can always push and play with it more.
I do understand how you feel, I too have been trying to explore breaking away from using lines a bit, or at least breaking them up. Having a hard time understanding how to really translate planes and define form though... also rendering takes me longer and I lack patience!
I am personally becoming a huge fan of strong colours more than subtle, as well as use of texture in these situations.
Does it look, despite the looseness, like an finished artpiece? Do you look at it and think "Oh, this guy meant to kept it quick and loose" or are you more like "That's an unfinished painting, someone must be halfway through the process here"
Again, this answer is very subjective. What you intend and what I see are not necessarily the same thing. There is definitely room for improvement and cleaning up your forms. But like with any painting, we can always push things further. It's learning to listen to the painting telling is when it is done and accepting that.
That being said, if you tidied a few things up and cleaned up the border, presenting it in a somewhat neater fashion, this could definitely pass for something more finished.
Good work, keep at it.
