Crazy doing this in LMMS. But it is great for a lo-fi aesthetic!
I will say I think you can stand to create a double-track of the guitar synth using a slightly different patch. Part of what makes guitar sound so dynamic is having 2 slightly different instances of a left and right guitar 100% L/R panned, so that you get this wide wall of sound feel.
Compositionally, this is fantastic. Just needs some final touches of the following: approximate or achieve sidechain of the bass to the kick, same with other elements sidechaining to the snare, double tracking guitar synth, lowering volume of hi-hat, gentle panning of instruments left and right for more spacious stereo image -- including FX such as delays. Finer adjustment of volume levels -- some study on mixing for your favorite genre will go a long way!
I would also eliminate the clap sample and change it to another percussion instrument such as a clap stack or china cymbals.
Also, congrats on FP!
NGADM score differs from NG rating because I am rating 4.5 stars for personal preference (I love the doom-ish elements). NGADM score 6.5/10, or 3.5/5, by reason of mix and master being a bit muddy (see 48 seconds) with shoegaze/reverb and spacial treatment of instruments (lacking double-track and/or defined bass in the sub region).
