No. Finish Boss, and make it good. THEN start your next project. If you start a second project in the middle of another project, you'll end up with 2 poopty projects instead of 1 decent one.
Don't post this to the exchange. I have many tracks like yours...but I haven't posted any of them. Take your time. Make something original, and make sure it is something you and the people on here are proud of.
