With over 50,000 projects competing for attention, it is hard for any one project to get a lot of the attention. Sometimes a particular project catches people's fancy and becomes very popular, but most projects get only a handful of views.
You could start by putting links to your projects (or your gallery) in the forum, so that people can get there easily. You could also try writing advertisements for the projects, telling people what sort of excitement they'll get by visiting your projects. Don't lie about them, though, or people will lose trust in you and not pay any attention to your messages.

You should also show interest on other people's work to get them interested on your projects. Posting ads on other people's projects without taking a look at their projects might not get you as much attention as if you really engage in a nice exchange of ideas with them. Try looking for projects that are interesting to you and say why you think they are interesting, and then asking them to visit your project since you have a similar interest.
