Unit 66 plans

This is a test piece I have done for Unit66, this is a concept environment, I have used multiple styles to fill in the drawing, there is pastels, felt tips and pencil. This shows how different styles effect the drawing. I have linked the image below. From this drawing I have concluded that of the styles i tried I like pastel and pencil, but I dislike felt tips. A lot.
For the background I used pastels, pastels can create a good effect by smudging and smearing. I epically like the ability of being able to mix colors together which can create some really good effects.
I dislike Felt tips because of the texture and feel they create, there is no control over color mixing like with other styles and there is also no control over gradients or how you want to style the colour because of this.
