Very good. Continue developing the things you're best at and the other areas will look better because the best booster is developing what you're best at. Your selfconfidence increases as well, increasing your productivity or time put into one piece.
This method is as effective as it can be dangerous though. All the time you climb a singleway ladder which only leads you up. A big leap to the other skills of the trade proves a brave task the higher you step.
There might be a bridge on a reasonable altitude, or a friend, already soaring high, who aids you in your trials. I can assure that you will find bridges, patience is a virtue when it comes to the trade.
What I ask of you is consider this: Do you want to take the step up towards the heavens, developing a bland span of areas in small scale, fully mastering one craft, or discover what is hidden beneath and develop a wide area of medias nurturing little specialization.
The latter requires great patience to specialize in a few areas and the first requires much humbleness of you, not easily derived from the acknowledged selfconfidence.
I chose to climb high until my knuckles hurt.
Make your move.
