My current room is 17 by 21 and I had the forests in here for about 6 months before upgrading to the Dali Euphonia MS-4's (my current speakers). Upgrades depend on what you think is missing. I know this sounds silly and literal, but when you say small, do you mean sounding or looking? I know that sometimes smaller speakers in a larger room can fool me into thinking they're not up to the job, when in reality they are great. I loved my forests in my room; however, the Dali's have shown me how much I was missing in low-end authority and detail (and what I loved about the Forests was their detail, so that's saying something).
So what are you missing? Bass, detail, soundstage size? I think if you like the Hawks you'll like the Forests (I auditioned both and got the Forests). If you're looking for a HUGE jump, then I don't know if the forests will provide that. I can't speak to the Monitor Audios, although I've never loved their speakers. The winds certainly would be something to keep in mind if you're staying in the totem family. I know I always feel weird when someone pushes what they have in their listening room, but given that you like Totem's sound and listen to a variety of music, I think the Dali Helicon MK II's would be up your alley, sonically and aesthetically.
