The main point was to show OP an other way of coloring that some artists use in case of digital coloring. And also maybe OP can see some of the mistakes he/she has made (the lack of highlights resulting from reflection from other surfaces for example)
OP, I also suggest you should try coloring everything at the same time because it tends to look glued together of different pieces if you do it otherwise.
