So is there a point where you stop sounding ridiculous due to exaggerating tones?

I've been learning Thai for about six months now and I'd say it's going pretty well. Slow but steady. However, while I do get praise for getting the tones right most of the time - I can tell I'm exaggerating them. It sounds quite forced, I guess. I've noticed similar pronounciation in other learners. I'm wondering if there's a point where people tend to start sounding more natural or what your experience has been? I'm not sure if I need to work on softening the tone expression or if it will just happen naturally as I become more confident I'm getting it right without having to be so exaggerated.
