its not a matter of agreeing or not, its more a matter of painting something that looks a lot like someone elses style. This can be done by shapes or colors etc. In this case Phoenix is saying that the overall style and color of the image is very similar to that of Tonge's usage.
No biggy but its good to point it out so you keep true to your own style
Yeah, I think I understand you on that - you mean all those things together - on that I agree... ...I'm just still developing my painting style (I think I already did a good job on space art scene and now I'm trying to add a new technique - digital painting) and trying to figure it all out.
Just because somebody else uses a certain style doesn't make it their own. If you are developing into or trying another way or form then work with it. I can't say that I know of a single artist that claims that the way they do things or a certain style belongs to them. These people are purists that expect something completely different from everyone. Variety of methods tried and practiced is what makes an artist well rounded and skilled.
