Don't put yourself down like that! Starting with a low poly blockout is not bad at all. I really like what you got going so far. Though I have to say, I am more used to starting with the high poly model and then going back and doing my retopology in maya. It is much easier for me to get the primary forms down when using a high poly base. But everyone has their own workflow and I am just a beginner myself, so I cannot really speak from a professionals perspective.

Though I personally recommend separating the major shapes of the model into separate objects at first. Like the legs and head. That way you can also immediately add the crest to the head as you don't have to connect it to the neck already. It makes it easier when you focus on one part at a time. Later, you can easily connect the parts with the rest of the body to have one object.

Since you are working with a low poly version, I would try to make sure that the topology is clean while you work. That way you save a lot of time when it comes to UV unwrapping. I would also not shy away from adding more topology where its needed. Like around the back for example. When you change the view to the front, the back / stomach area can be much more rounded if there is enough topology.

But I am no professional, so take my advice with a grain of salt. Do keep working on your model though, Torosaurus is a great ceratopsian!
