I wouldn't qualify myself as a pro, but the advice I can give you is to improvise as much as possible.
Since you probably have a couple of tricks under your belt, jam along midi files or even your favorite song. Just try to improvise solos. Concentrate on timing and feeling rather than speed, speed will come naturally.
I personnaly love to improvise over I really enjoy jamming over I'm ready for love by India Aerie (Hope I spell it right). Some may laugh but this is a great song to work your "feeling skills".
These exercises will enhance your creativity and help you understand the many techniques you've learned in the past.
I was able to break a big "plateau" by jamming over songs.
Hope this helps, keep jamming!
