i think you should get rid of the render on the right. it looks really out of place. its overall too bright. add some more brushing to make more happen. its simple but good job.
nice and flowing, but imo a bit oversharpened. artefacts are quite noticable. try erasing the sharpened layer slightly on places where it started to distort colors and shapes. otherwise, really good work! :>
use another render with shapes and things u like and set to color dodge or screen and lower opacity.. or u can make
Nice job man. if your having trouble with text placment try placing it on the space to the left where you put the line tool or somwhere around there. btw ashlee simpson is but is a joke lol @ the her doing the jig.
