Reading your comic, its a cute and lovely premise that's kinda rare to find nowadays! At the very least, its not one that's propped up on the front covers of tapas sadly but you have a charming idea and it's so refreshing to see!
Some things I love:
Your rendering is amazing! I can really tell that its something you like to do because its well done and highly detailed! The colors are really vibrant and match super well to the tone of the comic, so I think you've done a lovely job painting the mood and image of all the scenes. The characters are really fun too, I feel like this is going to be a cast of characters I really enjoy!
Some things I noticed that could be polished:
I mentioned earlier that I thought you really focus on the render...and that's because everything else art wise suffers a bit. I can see your greater vision in scenes, especially when you draw backgrounds and wide shots that show multiple characters, but technically they're weak. It's like baking a cake, the frosting on the outside can be gorgeous but if you cut it open and your cake isn't good then you don't have the greatest foundation to work with. I think where you are now is a good start but really focusing on refining the body and backgrounds will help you so much in the long run
Maybe it's something you'll focus later down the line, but the title is misleading to what the story is? From the title, I assumed that this would be a story that focused on the two brothers that learn to become dads together HOWEVER this is actually Hector's story in becoming a dad when Zack already has an established family. This is just something to be aware of as new readers come into the story, especially since the first 9 episodes really just focus on Hector and his desire for kids.
Small nitpick I noticed as an asian american myself, but I'd be wary of leaning too far into stereotypes, especially for Azalea and the tiger mom stereotype. Of course, stereotypes aren't necessarily BAD (imo at least) and I do not know your background so you could be writing from your own experiences, but my first introduction to Azalea as a wok wielding wife and mother didn't sit super well with me? I get it from a comedy standpoint as I do love a little physical looney tunes comedy but I'd recommend you tread carefully as you continue to flesh out her character (and any other similar characters!)
Final thoughts:
It's a strong premise with bright colors and fun characters which is a recipe for something at the very least I'd enjoy! As you start to move into episodic slice of life stuff, I'd use it to take the opportunity to slow down and work on foundational art techniques that will help you in the long run for your journey as an artist. The critique part may seem bigger than the compliments part but I promise those are mostly small things that do not damage your overall story
Let me know if you have any questions or want me to look at anything specific!
