@Kryzon thanks for that, I completely understand what you mean about the sharp/soft shading and was actually looking over that the past couple days. I didn't use an air brush but I did smudge a darker colour over the top which ultimately rendered a similar effect. Definitely over using that shading technique can leave you with a blurry image none the less.
Fundamentals are definitely something I'm coming to terms with as I'm progressing.
@a light breeze thanks also! So, I understand my character has no elements of shading or shadows which would actually enhance the scene way more. My issue was probably the fact that I didn't care to add any shading or shadow. (I'm drilling myself now to stop being lazy!)
the other two things you mentioned are great ideas which I'll give a go! I like the thought of a light from a constant direction and adding foreground shading!
@tyree another thanks! I took your advice but didn't like having black lines around my background images almost like a stroke. I stole that technique from someone in my class and I liked it lol I'm just not pulling it off too great at the moment. I'll still play around with the idea though 'cause you never know !
