"been using the Vienna opening with white" ++ Good

"the Rousseau gambit with black" ++ Bad

"Should I learn more openings before mastering these?" ++ No. Just play and analyse your lost games.

"work on perfecting them?" ++ Yes. You gradually accumulate experience.

"sticking with these openings, how can I get more solid" ++ Just play and analyse your lost games.

You were doing well in the opening against the fianchetto.
4 h4 intending 5 h5 is sharper, but 4 f4 is good too.
5 e5 is OK, but 5 Nf3 developing a knight is more active.
6 Nb5 is weak. You play the same piece twice. The knight is not active on b5, it should go to the center Ne4. Sharper 6 Qf3 attacking Ra8.
7 Qd3? is a mistake. It puts your queen in the diagonal of Ba6.
26 Qb7? loses the rook after 26...Rha8 with mate threat Ra1# and Re3 still hanging . Better 26 Qc5 threatening 27 Nf5+
23 Kc4? is a mistake losing pawn b2.
38 Kf4? runs into the fork Nh3+
42 Ne1? misses Ng8+ and Nxh6
65 Kf7? loses the knight and the game after 65...Rc6. 65 Kd7 would have held the draw.
67 Kg8? loses the knight after 67...Rd7. 67 Ke8 would have held the draw.
68 Ne5+? loses the knight after 68...Kf5. 68 Kf8 would have held the draw.
69 Nc6? loses the knight. 69 Ng4+ would have held the draw.
You were winning in the opening, but you lost the endgame.
Conclusion: your main problems are in the endgame, not in the opening.

i think you should learn another opening with black (to have one against e4 and another against d4), but besides that, you should focus on mastering these and your perfecting your middlegame.

Thank you guys for your feedback. It is much appreciated. Do you suggest any openings for black that may be more solid than the Rousseau? I think I like the Rousseau because it is much like the Vienna. I don't think I am at the level to remember 100 lines yet. Even more importantly, what is the issue with the Rousseau? I think I need to still learn the basics of how to choose an opening.

Also, I agree with both of you about my middle and endgame. Especially the endgame. Maybe I will start focusing more on that first.

Thanks again!

The Rousseau is like the vienna, but the king is much weaker, and it is much riskier. This is especially so if the opponent tries to blow up the board, where your king is a sitting duck, especially in the rousseau.

Now, lets see what happens in the rosseau:

This is just a quick analysis of mine tho. There are people far more qualified but I just wanted to say something.

TLDR: Both gambits make your king kinda unsafe, but Rousseaus gambit allows white to get a VERY quick and very big attack with their development.

I recommend two knights if you would like that.

Also, for against 1. d4, you could use the kings indian, or even englund gambit (as you seem to like trappy gambits) but I am not sure if you even need a d4 opening as you did not include that in the post.
