Firstly, welcome aboard and congrats on your 1st remix.. The thing that hit me straight away, on the 1st listen was the lack of a bass-line. This is a fairly straightforward tune with a common, '4 chord trick'. (C-Am-F-G) is a structure, responsible for more hit songs, in the 60's than probably any other. As such, it's one our ears are familiar with and accustomed to and it needs variation to make it sound 'fresh'. Although Rob's original bass-line sticks rigidly to the 'root' notes, to bed down the structure, a bass-line could have been a neat way to vary the feel of this.. Using 3 similar sounds for 'chord', 'arpeggio' & melody blends the mix a bit too much and buries the piano, melody line in places. The drums DO vary in places and the fills are nice but the kit, overall sounds a bit dry, (emphasised by the lack of bass-line).. The sequencing structure with identical, short note lengths, make for a mechanical feel to the tune. Good 1st effort and please don't be put off by the lukewarm responses to it.. I hope it encourages you to immediately start on your next remix and I look forward to hearing it..
