Always another way...
Hello Jasmina. Great class again!
I'm no beginer at photoshop, been using it for 20 years, I think.
But somehow, there's always some other way to do things, more tips, more functions to use... I work with an older version, so I didn't get to try that new select object tool, looks fun! The colored pencil sketching tip is just genius, I will surely start using funky colors to sketch from now on.
Here is my before/after. My sheet is bigger than my scanner, so some stiching was needed as you can see. I did a whole collection of animals on hand crafted paper with a cola pen and this is the best piece. Each sheet of paper is different and has a different color (it's made from recycled clothes, each sheet is truly unique and beautiful). The best piece of the collection ended up being the rhino, and it was on my least favorite colored paper. Too warm, too mossy. 
Hope you like it!
