1. How does the size of the texture image effect what is displayed in the render?

The size of the texture image can effect a lot especially in the tender view because it could be black or grey in the perspective view port but in the render the image can show. I can also be blown out and have major stretching so it is important to utilize the image in the uv editor and the bump maps that match the color image texture you use on the object.

1. How does the resolution effect the quality of the render?

The resolution of the image is extremely important because it can have a pixelated stretched out look if the image is to small. also if the image is to big and is not properly sized to the object you could get a close up of not what you want the texture to be.

Finale render for SAL
this was a pretty fun project was challenging but fun

What worked and what didn’t? 
Detail work worked really well and copying over one finger and duplicating really helped with the time and then remeshing it back on the hand itself. 
What would you do differently next time?
Back up my files more often and make sure the files are not corrupted. And also make sure my mac book is up to par and be carful about not running anything else in the background to have the computer crash and freeze on me so the files don't get corrupted and then won't open later. 
Did you encounter any major issues, if so how did you adapt? 
My szbrush files were corrupted three versions back and the stool

this is an example of what it looked like but it was the entire view port and then it would crash multiple times.
How did the end result come out (give yourself honest feedback)? 
i think model came out pretty well i would probable liked to have put a little more time the details of the arm but i like the end result.
