W O W :o I just got back to this part of the forum after posting for a few days in Finished Projects, and I am totally amazed and humbled by the incredible replies! THANK YOU ALL for all your encouragement. I’ll try to get to everyone now…
Sonix: Thank you so much for the great feedback. I’ve been whipping up some potential textures in Corel Painter 8, and I’m hoping they’ll work out. Since this is all going to be one big mesh and will consequently be the UV mapping nightmare of all UV texture jobs, I have another approach in mind that will use multiple materials on the one mesh but using textures that will be designed so they flow into one another in terms of colors. It will be tricky. If it doesn’t work out, I might take you up on your kind texture offer. The plan is that every single thing in the scene will be extruded from her. Everything that has been shown so far is all the product of extrusions, so this is like the ultimate personal challenge to do this entire thing all from one mesh. I have some wild ideas in mind, so hopefully it can all be realized in time for the deadline. BTW I’m at Warwick.net in the US 
Gabio: I’ll try my best
Hopefully when Expose 3 rolls around we’ll have a growing number of potential Blender artists submitting cool images for high profile contests like that.
Gr8RedShark: Thanks. You’re right about the thickness. I toned it down. Check out my update to be posted below. I’m thinking she’s more flowerlike than cactus (flowering cactus…? nah) so I’ve tweaked the top of her head petals 
Jay Eff:
Thank you. If this ever makes it to Expose 2 I hope the judges feel that way 
Modron: Thank you very much. Yes, you were right about the petals. I have never had any good results with the warp tool. Maybe I should try it. It’s great to have the undo function available so we can get a little more adventurous with experimenting on meshes. That was a great chip btw! and rat! Very nice indeed.
thorwil: The perspective might change depending on how much of the scene I finish, so the crownlike emanation of petals from her head might look better once they are adjusted to accommodate the surrounding scenery. Also, one or two petals might become something else because this is going to be somewhat surreal. She is a creative spirit of sorts and will be emanating lots of stuff 
Enos Shenk: Thank you very much for the encouragement! I thoroughly appreciate it and feel motivated to go the distance 8)
Erufailon: I’m running - more like accelerating, pedal to the medal for sure
to infinity and beyond…
three-de: Thank you very much. I’ve been working very hard on trying to improve my organic modelling, so hopefully that comes through in a piece like this and helps the model look more natural (or maybe in this case supernatural).
Cyanid: Thanks!
dante: Thank you dearly for those words.
See my post below for better images of the front and now back of the current model.
