(I listened only to the most recent download in the thread.) I do like this track; it has some nice brass work with some decent samples. Kirkhope's original is a pretty slow song but your rendition is very good. jjmusic has some great ideas on song development. A few of my own thoughts, mostly related to production and mixing:
1. Production-wise, the track in general feels a little "oppressive;" there are lots of lows and mids but few upper frequencies to brighten up the mix. 1:01 brings some nice relief but you could still add more. More on this later.
2. Beat at :24 is a good start, though I'd play around to see if you can develop a rhythm that grabs more interest. Maybe try half time at this part? More of a personal preference maybe.
3. Beat at :45 would be a nice time to bring in some upper frequency range percussion-rides, tambourines, brushes, etc. You've got plenty of room in the frequency spectrum.
Below is the spectrum analysis of your track at :45. Notice the dropoff beginning around 4-5k. That's where your "brightness" and clarity in the mix comes in.
For comparision, I quickly screengrabbed my "Life of a Spy" track, which is a little similar to yours I think. Notice the highs, which gives the track clarity and brightness. You've got plenty of room up there above 5k to add some percussion, or even boost the highs a bit on some of your bells/chimes/vibraphone sounds.
4. Guitar at :44 does sound out of place. It's too dry for the sounds that you have around it, and sits too upfront in the mix for that amp choice.
5. The texture and hits at 1:01 are pretty awesome. Again, room for more in the high end! Nice powerful sound there, though.
6. I think you need a nice driving beat at 1:30 to bring the song forward. Otherwise, it sounds like it's dragging a bit there.
Overall, a very good start. You've got a good sense for ebb and flow. Samples sound pretty good. 1:01 shows a good sense for texture and leaving space in the mix for certain instruments. Good luck with this!
