I agree with C-Thug. Just mix your rhymes. Sometimes I try to rhyme in dutch or german too. I know you`r problem tho, I also can wriite kinda better in english. But aint nothing wrong with that, caus you can reach a bigger crow if you make it oneday. And the other languages, you can practice on that. Over here, in the netherlands, there are allot of MC`s that rap english, dutch and marrokan etc. all together.
