An Irish Red Ale is a very simple beer, the flavor/aroma all comes from the malts, little hop flavor or aroma (if any). All you need is 2-row, a bit of caramel, a spattering of roasted barley, and bittering hops. If you want to add more, like oats or some munich that's probably fine.
If you are going for a more traditional Irish Red Ale, I would suggest removing the amarillo, and halving (or eliminating) the flameout addition, also remove the melanoidin and halve the caramel, then add around 4 oz of roasted barley (Irish Red Ales get their color from the roasted barley). If you want a hoppy red ale instead, add more hops to the end of the boil and be aware that it's no longer an "Irish Red Ale".
If you want it to be maltier, mash higher rather than adding more malt. Whenever I design a recipe I force myself to remember the "KISS" principle.
