filling my sketchbook

I have three concepts which are not yet all applied to website and pdf presentation. But already now I know that with one it won't be so easy - the concept with pictures. I wanted to use different colours but it will disturb projects for portfolio. That's why I will be deciding between concept of "t" which contains only cmyk blue and black (for portfolio blue can be changed) and "collage" concept which is only black and white.
